"The remote web server is running nginx, a lightweight, high
performance web server / reverse proxy and email (IMAP/POP3) proxy. 

According to its Server response header, the installed version of
nginx is between 1.0.7 and 1.0.14 or 1.1.3 and 1.1.18 and is,
therefore, affected by a buffer overflow vulnerability. 

An error in the module 'ngx_http_mp4_module' can allow a specially
crafted mp4 file to cause a buffer overflow and can potentially allow
arbitrary code execution. 

Note that successful exploitation requires that the 'mp4'
configuration option is enabled and the module 'ngx_http_mp4_module'
is enabled. Nessus has not checked for either of these settings.");
